Simple PSU for DIY

Proto PSU is an easy to assemble DIY kit that is designed to make it easier and cheaper to have a dual rail power supply typical of DIY synth for prototyping purposes. Its 4 layer PCB design uses through hole components that are clear and easy to solder. It is versatile, it can either be a breadboard attached supply, an internal case supply or a module style power supply depending on how you configure it. There is no need for a specialist AC supply or to use mains electricity, it runs off a 15VDC adaptor.
